The increased performance and the rapid shift from traditional handsets to consumer computing device post a number of manufacturing and supply chain challenges for fabless chip makers. Dr. Roawen Chen of Qualcomm says the scale of the challenges also creates an “extreme stress” for the existing foundry/fabless model to defend its excellence in this dynamic landscape. In a keynote talk at The ConFab, titled “what’s on our mind?” Dr. Chen will deliberate on a number of headwinds and opportunities.

Jean-Eric Michallet, Hughes Metras and Perrine Batude of CEA-Leti describe how the research group has already demonstrated the successful stacking of Si CMOS on Si CMOS, achieving benchmark performance for both layers of transistors. The main process challenge is to develop a sufficiently low-temperature process for the top transistor layer to limit the impact on the lower transistor layers.

Phil Garrou continues his analysis of the IMAPS Device Packaging Conference with a review of the keynote by AMD’s Bryan Black, titled“Die Stacking and High Bandwidth Memory.” Black stated that “…while die stacking is catching on in FPGAs, Power Devices, and MEMs, there is nothing in mainstream computing CPUs, GPUs, and APUs …HBM Stacked DRAM will change this!” Garrou also reviews the newly announced STATSChipPAC FlexLine, which uses eWLB technology to dice and reconstitute incoming wafers of various sizes to a standard size, which results in wafer level packaging equipment becoming independent of incoming silicon wafer size.

CEA-Leti will demonstrate its new prototype for wireless high data rate Li-Fi (light fidelity) transmission at Light + Building 2014 in Frankfurt, Germany, March 30-April 4. The technology employs the high-frequency modulation capabilities of light-emitting diode (LED) engines used in commercial lighting. It achieves throughputs of up to 10Mb/s at a range of three meters, suitable for HD video streaming or Internet browsing, using light power of less than 1,000 lumens and with direct or even indirect lighting. With this first proof of concept and its expertise in RF communications, Leti forecasts data transmission rates in excess of 100Mb/s with traditional lighting based on LED lamps using this technology approach and without altering the high-performance lighting characteristics.

Toshiba Corporation announced that it has brought a civil suit against Korea’s SK Hynix Inc. at the Tokyo District Court, under Japan’s Unfair Competition Prevention Act. The suit seeks damages for the wrongful acquisition and use of Toshiba’s proprietary technical information related to NAND flash memory, which Toshiba pioneered in 1987 and now jointly develops and produces with SanDisk Corporation of the U.S. SanDisk this week also filed a separate lawsuit against SK Hynix for theft of trade secrets.

This week, imec presented the development of fullerene-free organic photovoltaic (OPV) multilayer stacks achieving a record conversion efficiency of 8.4 percent. The imec team now proposes a simple three-layer stack to improve the spectral responsivity range. This device architecture comprises two fullerene-free acceptors and a donor, arranged as discrete heterojunctions. In addition to the traditional exciton dissociation at the central donor-acceptor interface, the excitons generated in the outer acceptor layer are first relayed by energy transfer to the central acceptor, and subsequently dissociated at the donor interface.  This results in a quantum efficiency above 75 percent between 400nm and 720nm. With an open-circuit voltage close to 1V, a remarkable power conversion efficiency of 8.4 percent is achieved. These results confirm that multilayer cascade structures are a promising alternative to conventional donor-fullerene organic solar cells.

STATS ChipPAC, a provider of advanced semiconductor packaging and test services, has designed and implemented an innovative new manufacturing method that is a significant paradigm shift from conventional wafer level manufacturing. This breakthrough approach, known as FlexLine, delivers an unmatched level of flexibility and cost savings for wafer level packaging (WLP).

CEA-Leti announced this week it has fabricated ultra-scaled split-gate memories with gate length of 16nm, and demonstrated their functionality, showing good writing and erasing performances with memory windows over 6V. The devices provide several benefits especially for contactless memory applications, such as enlargement of the memory window and increased functionality. Also because of an optimized fabrication step, the devices allow better control of spacer memory gate shape and length.

EV Group (EVG), a supplier of wafer bonding and lithography equipment for the MEMS, nanotechnology and semiconductor markets, this week announced that its patented NanoSpray conformal coating technology is now available on its newly introduced EVG150XT resist coating and developing system for high-volume manufacturing (HVM) semiconductor applications.  NanoSpray provides conformal coating of structures that have vertical sidewall angles—such as through-silicon vias (TSVs), through-glass vias and through-substrate vias used for 2.5D interposers and 3D-ICs—with thick polymer liners and photoresists.

3DIC memory, and therefore all of 2.5/3D technology, took one step closer to full commercialization last week with the HBM joint development announcement from AMD and Hynix at the RTI 3D ASIP meeting in Burlingame, CA. Bryan Black, Sr Fellow and 3D program manager at AMD noted that while die stacking has caught on in FPGAs and image sensors “..there is nothing yet in mainstream computing CPUs, GPUs or APUs” but that “HBM (high bandwidth memory) will change this.”  Black continued,  “Getting 3D going will take a BOLD move and AMD is ready to make that move.” Black announced that AMD is co-developing HBM with SK Hynix which is currently sampling the HBM memory stacks and that AMD “…is ready to work with customers.”

ABI Research verified that Intel has a leading position in the mobile processor technology race; launching the first 22nm mobile application processor. The 22nm quad-core application processor (Intel Z3740D) was found in a Dell tablet that was recently launched for the Christmas season. “2013 saw a number of new processor launches with 32nm and 28nm technology (most from fabless companies) but Intel has used one of its core advantages [process technology] to pass them all,” Jim Mielke, VP of engineering at ABI Research, commented. “The 22nm process node used for the Z3740D is not just the smallest geometry in a mobile device today; it also introduces a new transistor. The core transistor structure used in the 22nm Z3740D is quite different than structures used in previous generations. The core transistor found in the device ABI Research analyzed has a gate that surrounds source/drain diffusion fins on three sides giving it the name tri-gate or 3D transistor.

North America-based manufacturers of semiconductor equipment posted $1.24 billion in orders worldwide in November 2013 (three-month average basis) and a book-to-bill ratio of 1.11, according to the November EMDS Book-to-Bill Report published today by SEMI.   A book-to-bill of 1.11 means that $111 worth of orders were received for every $100 of product billed for the month. “The continuing rise in equipment bookings clearly points to year-end order activity that is substantially stronger compared to one year ago,” said Denny McGuirk, president and CEO of SEMI.  ”This trend supports the current outlook showing a rebound in equipment spending for 2014.”

Soitec and CEA have renewed their partnership for the next five years. This new contract aims to support Soitec’s strategy for the electronics, solar energy and lighting markets.
